AUGUST BECK, OF CHICAGO, ILLINOIS.

QUILTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 400,039, dated March 26, 1889.

Application filed November 15, 1886- Serial No. 218,861. (No model.)

To all whom it may concern.-

.l-3e it known that I, AUGUST BECK, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Quilting-Machines, of which the following is a specification, reference bei n g had therein to the accompanying drawings.

My invention relates to quilting-machines, and has for its object the provision of a machine of this character which is simple in construction and efficient in action.

The following detailed description will fully explain the nature and functions of my said invention, and its scope will be pointed out in the claim.

The accompanying drawings illustrate what I consider the best means for carrying my invention into practice.

Figure 1 represents a side elevation of the greater portion of the machine, with the feed rollers at this side of the machine partly broken away. Fig. 2 is a top plan view of the machine, showing the power mechanism, said view also representing portions of the bed-plate of the two sewing-machines, and also representing, partly in dotted and partly in full lines, the devices for reciprocating the said sewing-machines. Fig. 3 is an end elevation of a portion of the machine, and serves to represent principally the power mechanism employed. Fig. is a perspective view of the machine. V

Corresponding characters of reference in the several figures of the drawings designate like parts.

A denotes the stationary bed-frame, which is suitably constructed with reference to the several parts of the machine that are supported thereon.

B designates the one and B the other of the two oppositely-arranged sewing-n1 achines,

- which are mounted side by side upon the bed frame, so as to bring their horizontally-disposed and vertically-reciprocating needlebars 1. in parallel planes, and thus equip the quilting-machine with two rows of needles, respectivelybelonging to one and the other of two separate and distinct sewing-machines. Both of the sewing-machines are supported so that they can be reciprocated bodily in a direction transversely to the direct forward feed of the fabric that is to be quilted. As

an efficient mode of supporting the reciproeating sewing-machines, their base-plates 2 and 3 are arranged to rest upon anti-friction rollers C, which in turn rest upon the main bed-frame, as in Fig. These reciprocating sewing-machines may be guided in any appropriate way, and the opposite edge portions of the two sewing-machines can be provided with interlocking flanges, so as to connect them together by a sliding joint, as at 4, Figs. 2 and 3.

The reciprocating movement of the sewingmachine B is derived from a cam, D, the shape of which may be varied, according to the pattern to be stitched, by a longitudinal bar, E, provided along one end portion with rack-teeth, which are engaged by one portion of an oscillatory double segment-gear, E. The other portion of said gear is engaged by a reciprocating rack, E carrying a couple of rollers, 5, which embrace the rotary cam D, whereby the rotation of the latter will, through the medium of said rack E and the oscillating gear E, effect a reciprocatory motion of the bar E. This bar E, by a screw, 12, is secured to the under side of the carriage 2, and its reciprocatory movement is transmitted to the sewing-machine B by a lever, 16, pivoted between its ends to the fixture 15, and provided along its end portions with the slots 17, in one of which a pitman, 18, is at taehed, and is pivotally secured to the end of bar E by screw 12, and in the other one of which is a pitman, 19, coupled by a screw to carriage 3. for the outer ends of pitmen 18 or 19 can be adjusted along the slots 17, in which latter it may be held by a jam-nut or other like device, and hence either pitman can be shifted toward the pivotal center of the lever to the required extent. This construction permits the stroke of one reciprocating sewing-machine to be varied relatively to the stroke of the other machine.

The cloth support or carriage comprises the four standards 6 (i, which are at their lower ends secured to be rigid with the main frame and at their upper ends adapted to support the cloth-rollers 7, that are arranged in pairs, one pair being allotted to each pair of standards. These two pairs of standards are re- By this arrangement the pivot speetively arranged at opposite sides of the pair of sewing-machines, whereby one pair of rollers'wi'll guide the material to one sewinc-machine, while the oppositely-arranged pair of rollers will guide the material away from the remaining sewing-machine.

Each sewing-machine is herein provided with a pair of standards, 20, provided with bearings suitable for a rock-shaft, 21., which rock-shafts are operated from a suitably-constructed power mechanism, and which is provided with cams or analogous devices for effecting, through the medium of ordinary or suitable cmlneetions, the np-and-down movement of the needlebar. I

The power mechanism herein shown serves to actuate one rock-shaft, which latter serves in turn to operate the remaining rock-shaft.

The transmission of motion from one rockshalt to the other may be attained by the employment oi the two gears one upon one l'Uttk-Sillfb and one upon the other, said gears being made of sufficient thickness to keep them in mesh and at the same time permit the two sewing-machines to reeiproeate in opposite directions.

Each rock-shaft 2i affords a desirable support for a series of shattic-carriers, Ii, corresponding in number to the number of needles carried by the needle-bar ol' the sewing-machine to which said roelesliaft is alism is provided with fast and loose pulleys, and carries a crank with pitman 39, which connects with a cam, 40, upon the rock-shaft 21 of one of the two sewingenachines. The driving-shaft 38 is also provided with a worm, 4:1, engaging a gear, 4:2, upon the rotary shaft 4-3, that carries the cam D, in which way the cam can be conveniently driven. from the said driving-shaft. A band-pulley placed upon shaft 2-38 carries a belt, (0, which runs over a small pulley on an extended end of one of the feed'rollers 7, and thereby serves to produce the feed. of the cloth.

For the broader purpose of this invention. the term sewingunaehine, who 3 specified in the claim, is intended to cover a sewing mechanism of any construction suitable for qn il ti n g.

\Vhat I claim as my invention is In a quilting-1nachine, the combination, with a transverse teed, of two sewing-machines having horizontal and vertically-reciprocating needle-bars, a bar, E, connected directly to one of said machines and by a pivoted lever to the other nmchinc, and a cam. for operating said bar E, in the manner and for the purpose set forth.

In testimony whereof I al'iix my signature in presence of two witnesses.
